	PR c++/15000
	* c-common.c (c_common_attribute_table): Allow
	handle_visibility_attribute to be called for types.
	(handle_visibility_attribute) When given a type, set the visibility
	bits on the TYPE_NAME.  When given a decl, don't set no_add_attrs
	so that we can check later whether the attribute was present. Added
	warning if attribute applied to non class type.
	* c-decl.c (diagnose_mismatched_decls): Updated rules for merging
	decls and checking that they are consistent.
	* common.opt: Added -fvisibility.
	* c.opt, c-opts.c: Added -fvisibility-inlines-hidden.
	* c-pragma.h, c-pragma.c: Added handle_pragma_visibility().
	* flags.h, tree.h: Added assorted support defines for overall patch
	* opts.c: Added parsing support for -fvisibility.
	* tree.c (build_decl): Set visibility for all decls to be whatever
	is in force at that time.
